Fly over the scarred canyons of Mars in this breathtaking video from European spacecraft

The strikingly diverse surface of Mars is captured in new orbiter flyover footage, providing insight on the events of the Red Planet's ancient past. . These trenches are hundreds of meters deep and several hundred kilometers long, and are accompanied by features called graben, which form when the ground between two parallel trenches fractures and falls away. impact some 4 billion years ago.

A still from ESA's new video of Nili Fossae, a region of Mars containing many valleys formed when water flowed over the Martian surface. "Much of the ground here formed over 3.5 billion years ago, when surface water was abundant across Mars," ESA officials wrote in the video's description."Scientists believe that water flowed not only across the surface here but also beneath it, forming underground hydrothermal flows that were heated by ancient volcanoes.

The Mars Express orbiter, which arrived at the Red Planet in 2003, studied Nili Fossae previously in 2014. Researchers used, along with digital terrain models of Mars to create the 3D rendering of the landscape used for the flyover video. This data not only aids in our understanding of Mars' past, but also helps inform scientists on where to land exploratory spacecraft in the future. to keep talking space on the latest missions, night sky and more!
